Privacy Policy
Calculator inputs
The calculators run in browser JavaScript. Numeric entries are not automatically sent to a calculation server, placed in the address bar, or saved in browser storage. Refreshing or leaving a page can discard them.
Copy, print, and export
Copying uses your browser clipboard only when requested. Printing uses the browser print dialog. CSV export creates a local download. Once you share an exported file or copied result elsewhere, its handling depends on that destination.
Analytics and advertising
No analytics, advertising, session replay, or third-party tracking integrations are enabled in this version. The application does not use cookies or local storage for calculator entries. Hosting infrastructure still processes ordinary web requests and may retain operational or access logs under its own terms.
Contact drafts
The contact page creates a local message draft. It has no configured recipient or submission backend, so names, email addresses, and messages are not sent by that form. Downloading or copying a draft is a user-initiated action.
Changes
If a contact provider, analytics service, or other integration is added, this policy should be updated to describe its real behavior before that service is enabled.
